Nevertheless, as evidenced by the different metabolic routes that glucose can follow, each individual brain cell does not necessarily metabolize glucose to CO2 and water. (khanacademy.org)
Indeed, a wide range of metabolic intermediates formed from glucose in the brain can subsequently be oxidized for energy production (e.g., lactate, pyruvate, glutamate, or acetate) (Zielke et al. (khanacademy.org)
Lack of oxygen or abnormally low sugar (glucose) levels in the blood can result in less energy for the brain and can seriously injure the brain within 4 minutes. (msdmanuals.com)

Most people think of paralysis as occurring when the connection between your brain and spinal cord is severed, that when you break your back, you also sever the spinal cord. (bigthink.com)
